Definitions
- the present invention relates to a safety indwelling needle comprised of a soft outer needle to be inserted and placed within a blood vessel and a hard inner needle which is fitted in the outer needle and pierces the skin of a patient to introduce the outer needle into a blood vessel.
- an outer needle (catheter) is inserted and placed in the human body to infuse the fluid through this outer needle.
- indwelling needles have been known to insert and place the outer needle using the inner needle fitted in the outer needle.
- the inner needle is discarded after placement of the outer needle in the human body, but it takes a certain time before the inner needle is discarded. Therefore, if an indwelling needle has no safety mechanism there is a risk of pricking the fingers etc. of health care workers by the inner needle during this period or a so-called needlestick accident occurring. If the patient is infected with the HIV virus or the like, there is a risk that the health care worker might catch the virus or the like from a needlestick accident.
- Japanese Patent Application Laid-Open Hei 3 No.15481 offers a cannula inserting device for retracting a needle hub, which might cause a needlestick, into a hollow handle by means of an urging means.
- Japanese Patent Application Laid-Open No. 2000-167051 Japanese Patent Application Laid-Open No. 2000-185096 etc. present technologies relating to a safety indwelling needle (puncture device) having a retracting mechanism for retracting the inner needle immediately after use into the holder sleeve. These technologies present techniques whereby the inner needle is retracted by means of an urging means when an actuating element is operated in a peripheral direction of the holder sleeve so that the actuating element is fixed to a cutout formed in the holder sleeve.
- the safety indwelling needles disclosed in Japanese Patent Application Laid-Open No. 2000-167051 , Japanese Patent Application Laid-Open No. 2000-185096 etc. are free from the problem of the wrong actuation due to unintended pressing, but these configurations need an actuation in the peripheral direction of the holder sleeve after retraction of the inner needle. Therefore, there is the problem with the devices which causes difficulties in handling, depending on the left or right handedness. In order to solve this problem, two types of products for left and right handedness need to be prepared, which causes to increase in the cost for manufacture and management, and also forces the users to select on e from these two types.
- US-A-5,205,829 describes an intravenous catheter comprising a holder sleeve and inner and outer needles.
- the catheter comprises an actuator in order to release the inner needle from the holder sleeve.
- the actuator comprises an actuating member having an engagement projection.
- the wing is arranged rear of the latch so that the inner needle is released from the holder sleeve by bending the actuator backwards.
- US-A-5,695,476 discloses a protection assembly for an intravenous needle according to the preamble of claim 1.
- the protection assembly comprises an actuator having an actuating member and an engagement projection in order to release the intravenous needle from the holder sleeve of the protection assembly.
- the actuator has a finger-engaging surface of concave shape and a finger-engaging surface of convex shape. Both engagement portions are arranged rear of the engagement projection.
- the document suggests to provide finger-engaging surfaces arranged rear of the projection in order to be pressed down to release the needle from the holder sleeve.
- the present invention has been devised under the above circumstances, it is therefore an object of the present invention to provide a technology for a safety indwelling needle which is almost never erroneously actuated and free from the problem of the actuation depending on the handedness.
- the present invention is directed to a safety indwelling needle according to claim 1.
- the inner needle (12) is a hard needle provided with an inner needle hub (12a) at the proximal end thereof. It is usually a metal, mostly made of stainless steel. The tip of the inner needle (12) is preferably beveled in order to facilitate puncture.
- the outer needle (11) is placed into the human body after puncture and usually formed of a flexible resin.
- the holder sleeve (1) is usually formed of a translucent resin or the like.
- the inner needle (12) When the inner needle (12) is punctured into the human body, the blood passes through the inner needle (12) and reaches the inner needle hub (12a). Formation of these portions with a translucent material allows for confirmation of the blood reaching the inner needle hub (12a), hence makes possible visual recognition that the inner needle (12) has reached a blood vessel.
- the inner diameter of the holder sleeve (1) is preferably set greater than the inner needle hub (12a) and set smaller than the proximal part of the outer needle (11) or the outer needle hub (11a), so that the inner needle (12) can be retracted thereinto but the outer needle (11) will not be retracted.
- string-like rubber (not shown), etc., may be employed other than a coil spring (8) which contracts when no load is applied.
- the movement path of actuation is adapted to be included in the same plane that includes the axis of the holder sleeve (1). Hence, the problem due to the handedness can be eliminated, differing the case where the actuation is made by the rotational movement about the axis of holder sleeve (1).
- the inner needle (12) and outer needle (11) are punctured into the skin of a patient.
- the flow of blood through the blood vessel is stopped by hand while the holder sleeve (1) on another hand is pulled away from the patient so as to withdraw the inner needle (12) from the blood vessel.
- the actuating member (6a) of actuator (6) is operated so as to release the actuator (6) from the near distal end portion of the holder sleeve (1).
- the inner needle (12) is urged toward the proximal end side of holder sleeve (1) by the urging means (8), so that the inner needle (12) moves, which is followed by the actuator (6) moving along the slit(2).
- the outer needle (11) will not retract into the holder sleeve (1)but remains at the set position, so as to be connected to an infusion tube, etc.
- the inner needle (12) to move toward the proximal end side of the holder sleeve (1) is moved and held until its tip is completely withdrawn into holder sleeve (1). Since the retracted inner needle (12) is pulled by the coil spring (8) which contracts when no load is applied, the inner needle (12) will not be exposed outside, whereby it is possible to prevent occurrence of needlestick injuries.
- a structure for directly lifting the actuating member (6a) from the holder sleeve (1) is adopted.
- the actuating member (6a) is moved away from the holder sleeve (1), the engagement between the holder sleeve (1) and inner needle (12) is released, whereby the inner needle (12) is withdrawn into the holder sleeve (1) by virtue of the coil spring (8).
- This action differing from a depressing action, almost never causes an erroneous actuation.
- the actuating member has an engagement projection which can be fitted into an engagement window formed in the near distal end portion of the holder sleeve, and the actuator is fixed at the near distal end portion of the holder sleeve when the engagement projection is fitted in the engagement window, and the engagement between the actuator and holder sleeve is released when the engagement projection is pulled up from the engagement window.
- the actuating member (6a) of the actuator (6) is formed with an engagement projection (6b) while an engagement window (3) is formed at the front part of the holder sleeve (1).
- this engagement projection (6b) is fitted into the engagement window (3), the actuator (6) is engaged with the holder sleeve (1), and the engagement between the actuator (6) and holder sleeve (1) is released when the engagement projection (6b) is pulled up from the engagement window (3). Therefore, the engaged state can be released by moving the actuating member (6a) of the actuator (6) away from the holder sleeve (1), hence this action, differing from a depressing action, almost never causes an erroneous actuation.
- the inner needle (12) fixed to actuator (6) is retracted into the holder sleeve (1) by virtue of the coil spring (8).
- the actuating member is formed to be flexible and is joined to the actuator by a joint rod which is located closer to the proximal end side than the engagement projection is.
- the actuating member (6a) is preferably formed to be flexible and joined to the actuator (6) by joint rod (6c) which is located closer to the proximal end side than the engagement projection is, this facilitates smooth actuation.
- the outer needle (11) is slightly pushed out by the second digit of the right hand, for example, so as to separate the outer needle (11) from the inner needle (12).
- the second digit is located around an aftermentioned cutout portion (1f) of the holder sleeve (1) Therefore, the second digit is present slightly forwards with respect to the actuating member (6a). This allows the second digit to raise the actuating member (6a) immediately when the inner needle (12) needs to be retracted.
- the lift abutment (6d) on which the finger is abutted when the engagement projection (6b) is pulled up from the engagement window (3) is provided at the distal end portion of the actuating member (6a).
- the lift abutment (6d) is formed on the surface facing to the front as is shown in Fig.4 . It is also preferred that the angle ⁇ between the axis and the lift abutment (6d) is set at 90 degrees or smaller because this makes it possible for the lift abutment (6d) to hook the finger reliably.
- anti-slip such as serration is formed because this also enables quick reliable retraction of the inner needle (12).
- Figs.1 and 2 show a safety indwelling needle comprised of a soft outer needle 11 to be inserted and placed within a blood vessel, a hard inner needle 12, with an inner needle hub 12a, which is fitted in the outer needle 11 and pierces the skin of a patient to introduce the outer needle 11 into a blood vessel, and a holder sleeve 1 which has an open distal end and closed proximal end and is capable of holding inner needle 12.
- This safety indwelling needle is adapted to enclose inner needle 12 after puncture up to the needle tip thereof.
- Holder sleeve 1 incorporates an urging means 8 for urging inner needle 12 toward the proximal side and an actuator 6 which engages inner needle 12 at the near distal end portion of holder sleeve 1 so that inner needle 12 can be released and the tip of the inner needle is projected from holder sleeve 1.
- Actuator 6 has inner needle hub 12a fixed at the front end thereof and is formed with an actuating member 6a projected outside holder sleeve 1.
- a slit 2 which extends toward the proximal side of the sleeve so as to hold and allow actuating member 6a of actuator 6 to slide and assures the path of movement of the actuator 6 released from the distal end portion of holder sleeve 1.
- inner needle 12 is adapted to be released from holder sleeve 1 when actuating member 6a is moved away from holder sleeve 1 within the same plane that includes the axis of holder sleeve 1.
- a stopper mechanism 1a for arresting inner needle 12 having been moved to the proximal side of holder sleeve 1 is provided at the near proximal end portion of holder sleeve 1.
- the stopper mechanism 1a is to protect actuating member 6a of actuator 6 when inner needle 12 is retracted into holder sleeve 1 and is constructed by side walls 1b and a top cover 1c and provided with an arrest engagement 1e for holding inner needle 12 at the rear end of holder sleeve 1 when the needle has been retracted within holder sleeve 1 and a tail plug 1d for closing the proximal end of holder sleeve 1.
- urging means 8 a coil spring is employed.
- the outer needle hub is formed in funnel-shape having a flange 11b at a rear end thereof.
- a filter 13 is attached inside inner needle hub 12a in order for the patient's blood not to leak out.
- a cutout portion 1f Formed at the near distal end portion of holder sleeve 1 is a cutout portion 1f, in order to facilitate handling when inner needle 12 and outer needle 11 are punctured into a patient. That is, this makes it possible for the second digit to touch inner needle hub 12a. Further, provided on the proximal side adjacent to cutout portion 1f are holding portions 1g which enable the safety indwelling needle body to be held with the first and third digits when inner needle 12 and outer needle 11 are punctured into a patient.
- Inner hub 12a is fixed to actuator 6, so that inner needle 12 moves together with actuator 6 when actuator 6 is retracted.
- Actuating member 6a is connected to actuator 6 by a joint rod 6c arranged therebetween.
- Actuating member 6a of actuator 6 has an engagement projection 6b which is inserted into an engagement window 3 formed at the near distal end portion of holder sleeve 1, so as to keep actuator 6 to the side close to outer needle 11, opposing the urging force of urging means 8.
- the actuating member 6a may be formed at a front end thereof with a lift abutment 6d to which the finger is applied when the engagement projection 6b is pulled up from engagement window 3.
- the joint rod 6c functions as a fulcrum to the force acted on lift abutment 6d.
- Engagement projection 6b and engagement window 3 are formed at such positions that the path of movement of actuating member 6a is included within the same plane that includes the axis of holder sleeve 1.
- Triangular arrest engagement le is formed at the near proximal end portion of slit 2.
- an arrest engagement 6f is formed at the proximal end portion of actuator 6.
- the arrest engagement 6f of actuator 6 which has been moved by the urging force of coil spring 8 will easily pass over the arrest engagement 1e of stopper mechanism 1a. Since arrest engagement 6f and arrest engagement 1e after the former passes over the latter strike each other, the movement of actuator 6 toward the outer needle 11 side is restrained. If the storage of the inner needle can be attained by urging means 8 only, arrest engagement 6f and arrest engagement le are not essential. Further, though the function can be achieved by the urging means 8 only, the arrest engagement 6f and arrest engagement le may also be provided subsidiarily.
- Fig.3 shows a state before puncture into a patient.
- engagement projection 6b of actuating member 6a has been set in engagement window 3 of holder sleeve 1.
- inner needle 12 is kept at the near distal end portion of holder sleeve 1, opposing the withdrawal tendency of inner needle 12 into holder sleeve 1 by the urging force of coil spring 8.
- Fig.5 shows a state where a cap 20 is fitted.
- Fig.6 is a perspective view of cap 20 viewed from the opening side.
- Cap 20 covers outer and inner needles 11 and 12 in such a manner that they are ready for puncture and has an actuation stopper groove 20a in which actuating member 6a is fitted in an immovable manner in order to make actuating member 6a disabled.
- actuating member 6a is made disabled as long as cap 20 is fitted, wrong movements such as accidental retraction of inner needle 12 into holder sleeve 1 can be prevented.
- a needle structure 10 has an outer needle 11 made of a soft resin formed in pipe.
- This outer needle 11 has a thin-walled portion at the distal end thereof and thereby a degree of contact with inner needle 12 is increased.
- a funnel-shaped outer needle hub 11a is provided at the proximal end of outer needle 11 for connection with a tube of a medical fluid such as for infusion.
- actuator 6, coil spring 8 and tail plug 9 are inserted into holder sleeve 1 from a proximal end thereof.
- Joint rod 6c is fitted in slit 2 so that actuating member 6a is arranged on the outer side of holder sleeve 1.
- the actuator 6 is moved to the near distal end portion of the holder sleeve until engagement projection 6b of actuating member 6a is inserted into engagement window 3.
- inner needle 12 on which outer needle 11 is fitted is attached to actuator 6 from the distal end of holder sleeve 1.
- joint rod 6c is attached to the proximal portion of actuating member 6a while engagement projection 6a formed at the near distal portion thereof is fitted in engagement window 3.
- Anti-slip ribs 14 are formed on the front side surface of actuating member 6a.
- Fig.9 shows the released state where the insertion of actuating member 6a is disengaged. Shift from the inserted state to the released state is made by lifting the front part of actuating member 6a where anti-slip ribs 14 are formed.
- actuator 6 and actuating member 6a should be formed of a material having elasticity. This feature makes actuating member 6a displace easily, hence release easily from the inserted state. It is also possible to join actuating member 6a and actuator 6 with another element or configure part of actuating member 6a to be fitted into engagement window 3, by a separate part.
- the safety indwelling needle according to the present invention is a safety indwelling needle comprised of a soft outer needle to be placed in a blood vessel and a hard inner needle which is fitted in the outer needle to pierce through the skin of a patient so as to introduce the outer needle into the blood vessel, and provides a suitable configuration which prevents occurrence of erroneous actuation during usage, is not different in handling depending on the handedness, and allows for easy assembly.
